TAKE-DOWN ARCHERY BOW The invention pertains to an archery bow of the takedown variety, and more particularly to a takedown archery bow which is not easily discernible as a takedown type, and requires no tools or added components for assembly or disassembly.

It is well known in the art to have takedown archery bows that are not easily recognizable as being takedown bows, as shown in the patents to the following:

H. W. Groves, U. S. Pat. No. 3,156,230, issued Nov. 10, 1964;

W. D. Howard, U. S. Pat. No. 2,608,188, issued Aug. 26, 1952;

T. E. Helm, U. S. Pat. No. 2,228,823, issued Jan. 14, 1941; and

J. R. Tate, U. S. Pat. No. 2,163,503, issued June 20,

In an archery bow of this invention the limbs joins a center handle portion without the need for screws or other separate components. Screws are timeconsuming to install and screws or screw inserts may pull loose from the wood with use. Further, separate components generally require tools for assembly.

The construction of the present bow system features a pin and socket arrangement to align the joining parts and to provide the necessary structural support to resist the cantilever forces generated during the bow draw and shooting. The pin-socket of this invention provides a quicker, easier takedown without the need of tools for assembly and disassembly.

The present system has its attachment means hidden from view so that the takedown is not easily discernible. The pin-socket assembly and the installed bow string act to hold the bow limbs and handle firmly together.

The invention features a system to align the bow parts and prevent their twisting with respect to each other, independent of the cantilever-force-resisting system.

It is an object of the present invention to provide a takedown bow that is very easy to assemble and disassemble, without extra loose components or tools.

It is another object of the present invention to provide a takedown archery bow that is not easily discernible as a bow of the takedown type.

It is but another object of this invention to provide a takedown bow of very simple construction to provide economies in manufacture.

These and other objects of the invention will present themselves and become more apparent with reference to the detailed description and drawings in which:

FIGS. 1, 1a, and lb are isometric views of three embodiments of the takedown bow of this invention;

FIG. 2 is a cross-sectional view of the pin and socket assembly of this invention as shown in FIG. 1;

FIG. 3 is an isometric view of the joint between the limb and the handle portion of the archery bow shown in FIG. 1;

FIG. 4 is an isometric view of the joint between the limb and the handle portion of the archery bow shown in FIG. 111;

FIG. 5 is an isometric view of a pin and socket assembly integrally formed with base plates for either archery bow of FIGS. 1 or 1a. FIG. 5 also includes an optional ball detent device to hold the bow components together prior to stringing the bow.

FIG. 5a is an isometric view of a pin and socket assembly integrally formed with base plates for the archery bow of FIG. lb. FIG. 5a also shows an optional twist-resisting pin and socket device which may be used instead of the contoured joining surfaces.

Generally speaking, this invention is for an archery bow of a takedown type that is not readily discernible as a takedown bow. The bow has a pin and socket assembly disposed in the limb and handle junctures to accommodate the cantilever forces generated during the bow draw and shooting. The archery bow is held firmly assembled by the action of the pin and socket joint, the mated irregular contiguous surfaces, and the taut bow string.

Three embodiments of the invention are discussed.

The first embodiment has a joining juncture configuration characterized by a substantially V-shaped notch extending across the bow from side face to side face.

, The second embodiment has a joining juncture configuration characterized as a scarf joint extending across the bow from side face to side face, and having a substantially V-shaped notch which is the profile of the scarf joint as viewed from the belly side of a bow. The notch extends from the back to the belly of the bow.

The third embodiment comprises a scarf joint extending across the bow from side face to side face, a pin and socket assembly for anchoring the limbs to the center handle, and an additional pin and socket disposed in the joint to prevent the limbs from twisting with respect to the handle about the primary pin and socket.

Now referring to FIG. 1, a takedown archery bow is shown having a center handle portion 1, and two limbs 2 and 3, respectively extending therefrom. Two V- shaped notch joints, 4 and 5, respectively, separate limbs 2 and 3 from the handle. The notches extend across the bow from side face to side face. The limbs are prevented from twisting with respect to the handle portion when the assembled bow is strung. A pin 7 and socket 8 are disposed in each joint 4 and 5, respectively, as shown in FIGS. 2 and 3. The bow string 6 holds the limbs 2 and 3 and handle 1 in the assembled position when it is tautly secured about the limb ends. A liner or pad 9 may be employed in the joint to adjust the fit of the mating surfaces of the limb, and handle portion 1 or to prevent bearing failure in the wood. FIG. 5 shows a socket 8 and pin 7 that are integrally formed with a pair of mating bearing plates, 10 and 10', respectively. These plates will prevent failure in bearing, adjust the fit, and/or prevent twisting. The plates may have roughened surfaces to enhance bonding them to the wood, and they may be serrated or knurled to prevent their movement with respect to each other. The plates distribute the load over a larger area at the points of maximum stress. The fit of pin 7 into socket 8 may be a close slide fit to prevent accidental disassembly prior to stringing the bow or a spring-loaded detent 30 may be inserted in pin 7 to engage the hole 31 in socket 8 to prevent accidental disassembly.

FIG. la shows another embodiment of this invention corresponding to the second embodiment above referred to. This archery bow has a center handle portion 11, and two limbs 12 and 13, respectively, extending therefrom. The limbs and handle section are held tolimb 12 and the handle 11 is depicted as a scarf or diagonal cut having a V-shaped notch in the normal plane as viewed from a side of a bow. Joint 15 is similarly constructed to that of joint 14.

FIG. 4 illustrates the inner construction joint 14 in an isometric view with anchoring pin 7 and socket 8. The inner construction of joint 14 and 15 can employ integral plates with the pin and socket similar to that shown in FIG. 5. A liner or pad 9 may also be used similar to that shown in FIGS. 2 and 3.

Obviously the profile of the scarf joint shown in either FIG. 1 or FIG. la can be as well formed by complementarily curved surfaces as by V-shaped notches. The significant requirements are that the surfaces interfit to distribute the loads applied and that they be so formed that any twisting or turning movement would tend to cam the surfaces apart.

FIG. 1b is a third embodiment of this invention. Handle portion 21 is joined to limb 22 at joint 24, and limb 23 at joint 25. String 26 holds the assembled parts together. Joints 24 and 25 are planar scarf cuts extending through to the side faces of the bow. This joint is not characterized by a notch profile. In order to prevent twisting of the limbs with respect to the handle portion 1, the joints may use the assembly shown in FIG. a. The pin 7 is made integral with bearing plate 20. The socket 8 is made integral with plate 20'. Plate 20 has a twist preventing pin 17 which fits the hole 18 of'plate 20. When twisting forces are generated, the pin 17 prevents rotational movement of one of the plates with respect to the other plate.

0f course, other mechanism means may be employed to restrain the twist forces, such as using dimpling or detents to hold the plates together. Serrations, knurling, or roughening the contact surfaces may also be useful.

These and other modifications may be made. Those 7 changes obvious to the skilled practitioner are deemed to rest within the purview and scope of this invention, as represented by the appended claims. 1
